Boiler feedwater wastes consist of demineralized water <br /> into which phosphates, sulfates (as salts of sodium) and <br /> some organic compounds are injected. All chemicals used <br /> in the treatment of boilers have been reviewed and <br /> approved by the EPA. There will be no radioactivity, <br /> heavy metals or undesirable organic chemicals. <br /> Cooling water wastes consist of fresh water into which <br /> polyphosphonate and other organic compounds as well as <br /> hydrochloric acid are injected. The cooling tower <br /> treatment chemicals are reviewed and approved by the EPA. <br /> There will be no radioactivity, heavy metals, or <br /> undesirable organic chemicals. <br /> Demineralizer wastes consist of spent regenerant <br /> chemicals (caustic and hydrochloric acid) as well as <br /> those chemicals removed from the fresh water by ion <br /> exchange. Demineralization, as a process, does not add <br /> any chemicals other than HC1 and NaOH to the waste and <br /> since the source waters do not exceed the EPA/NPDES <br /> limits there will be no contamination of the waste with <br /> radioactivity, heavy metals, or undesirable organic <br /> chemicals. <br /> The total dissolved solids in the wastewater is estimated <br /> to be 7, 900 ppm. The injectate will be at ambient air <br /> temperature when it is injected and it will have a <br /> maximum pH of 8. 6 and an average pH of 7. 2 . Density is <br /> estimated at 1. 03 gr/cc. <br /> Concentration (ppm) <br /> Constituents Maximum* Average <br /> Cations <br /> Calcium 469. 8 363 . 5 <br /> Magnesium 129. 2 116. 5 <br /> Sodium 2 ,856.4 2, 083 . 0 <br /> Potassium 47. 0 27.4 <br /> Manganese 1. 0 0. 5 <br /> Anions <br /> Bicarbonate 954 . 7 850. 0 <br /> Carbonate 41. 8 8 . 1 <br /> Sulfate 300. 0 288 . 4 <br /> Chloride 5,974 . 3 3 ,775. 6 <br /> Nitrate 83 . 5 72 . 8 <br /> Phosphate 2 . 0 0. 8 <br /> Silica 450. 0 329 . 2 <br /> * The maximum concentration of any one constituent may not <br /> occur concurrently with that of other constituents. <br /> 7 <br />
